TNS series high accuracy full automatic three-phase AC
voltage-stabilized source is composed of TND (SVC) series high
accuracy automatic voltage-stabilized source; the three-phase phase
splitting adjustment guarantee various phase voltages stably and
safely; If the electrical network input is the three-phase
four-wire system, star shape (Y shape) connection, the output may
use the three-phase four-wire system or the three-phase three-wire
system, separately indicates each output current by three ampere
meters, monitor each output line voltage by a changeover switch and
a voltmeter.

Turn on the voltage regulator packing case, take out the Operation
Instruction Manual and the spare parts, read this (Operation
Instruction Manual)) carefully, and well keep it. Take out the body
of the voltage regulator, reliably put in dry and ventilating
place, press the door lock button by hand, the gate will
automatically open.

Wiring as per the instruction and marks on the connecting block:
Facing the terminal, the above three ones marked as the letter of
"A", "B", "C" respectively is three-phase input phase line, the
under three one marked as the letter of "a" "b" "c" respectively is
threephase output phase line, the terminal marked "N" "N
respectively is input and output common using median line.

After inspection wiring unmistakable, push the handle of C45
circuit breaker on faceplate to the "ON" position, the voltage
regulator immediately come on working adjustment condition, the
working indicating lamp is bright. Gyrates multi-purpose
change-over switch on the faceplate, observe whether various
voltage meter instructed is normal or not, after determined
unmistakable, then puts through the electric appliance which you
use. Overvoltage protection value 430V, when the output line
voltage is higher than 430V,voltage regulator automatically cut
output.

♦ Debugging Guide

The three-phase voltage regulator actually Is composed of
combination three single-phase voltage regulators, It Is ok to
connect their zero lines (N) together as common zero line (N).
Debugs, may debug single-phase separately: Inputs the single-phase
voltage from AO, by now, the voltage regulator at most above one
phase started to run, and carbon brush acts, pressed down the AC
contactor to make it close and test the correspondence voltage,
adjust 1R12 (1RP1) potentiometer on A-phase control panel, cause
Van as 220V; and then BN and CN phase separately (according to the
similar method). After finishing debugging three-phase separately
that mean the entire debugging have been completed, then input from
A, B, C, N three-phase electricity, output, automatically output
380V line voltage.

Prohibits using under the environment of caustic gas (for example
lampblack, steam and so on).

Attention for Earthing outer covering.

If you discovered the voltage regulator has the unusual smell or
belches smoke phenomenon in the use, please immediately push the
handle of C45 circuit breaker on faceplate to "OFF" position, break
the power source, then, dismantle the connected line and deliver
the whole machine to the company service department.

When purchasing this machine, please consider its load capacity
(Following Figure) and the actual total capacity of your each kind
of electric appliance used. It should leave full load allowance.

This voltage regulator input terminal must use three-phase
four-wire system, only then may be normal work; The out-terminal
may use three-phase three-wire system or three-phase four-wire
system according to the actual need. This voltage regulator cannot
be used in parallel connection.

Maintenance guide

Breakdown phenomenon

Reason

Overhaul and Service method

1. Failed to start

The input phase line connection is unreliable

Rewiring and inspect whether there is broken line place

Does not

have the input voltage

Survey whether the input

wiring column has or

not voltage with voltmeter.

2. Some phase no voltage instruction

The corresponding phase terminal wiring is unreliable

Inspects the condition of connection this wiring column

With the avonmeter ohm class measure whether the fuse burns out or
not.

3. After starting various phase voltages are not balanced, too high
and too low phenomenon

The input voltage is not normal

Inspect whether the electrical network is normal

The input

output line connect

Checkup wiring and correct

The input median line has not connected or the wiring is unreliable

Well connect the median line

Various phase voltages of the electrical network surpass its
voltage regulator scope

Inspecting the electrical network, it must off the machine load and
electricmotor that have high requirement ofthree-phase equilibrium.

4. On faceplate the voltmeter instructed various voltage is

The load is

seriously asymmetrical

Adjust each phase load, guarantee various phase equilibrium as far
as possible.
